Molin et al. 1986.
Gram-negative, rods, 0.7-0.8 x 1.5-3 μm, motile by one polar flagellum, asporogenous.
Colonies on nutrient agar are smooth, circular, and nonpigmented. They are
nonhemolytic on ox blood agar and do not glide on cytophaga agar. Fluorescent
pigments (pyoverdine) are produced on King B agar. No accumulation of
poly-beta-hydroxybutyrate as intracellular inclusions.
Metabolism is respiratory and never fermentative. Oxygen is the terminal electron
acceptor; nitrate does not serve as an alternate electron acceptor. The temperature
range for growth is usually 0 to 33 ºC, but 30% of the strains are capable of slow
growth at 37 ºC. The optimal growth temperature is 25 ºC. There is no growth at pH
4.5. No growth factors are required. Aerobic.
Isolated from refrigerated meat.
Unknown.
